Answer:
86
Step-by-step explanation:
x = 8
A line with "undefined" slope is a vertical line, whose equation is of the form ...
x = constant
In order for the line to go through a point with an x-coordinate of 8, the constant must be 8.
x = 8 . . . . . a vertical line through (8, -3)
D. zero
Since the graphs do not intersect, there are zero solutions.
(4, -6), (-10, -6), (-3, 1), (-3, -13)
If we add/subtract t to/from any x/y coordinate, we will form a line segment with length 7. Hence, (4, -6), (-10, -6), (-3, 1), (-3, -13).
